AN- Hi! I am back after ages... This is after beta reading. I have a cool beta reader! I will reveal it after some chapters. How was it? Please read and review.

Kai's pov.

I was walking through the hallways of the Black Diamond High School."Uh.. Which class is mine?" I asked the secretary who sat bored at the entrance desk,as I forgot to check the new changes in the timetable."2nd B. Mathematics." She murmured.

"What? 2nd B? A junior class?" I said in surprise. I walked to the junior building. I walked in, the door sliding soundlessly before banging harshly against its frame.

"GOOD MORNING SIR!" I was immediately greeted by a number of small gazes.

"Sir, are you our new teacher?" One among them asked innocently.

"Hn." I muttered. "Okay so our first chapter is addition and subtraction." I said sternly. "Okay, let's begin. I'll ask everyone."

"2+2?"

A boy answered "4".

"6+1" I asked.

"se..seven...maybe.." A girl answered.

"What do you mean by maybe?" I asked harshly. I felt instantly guilty when I saw her lip quiver as she attempted to stifle the tears, crying silently. "Okay sit down." I said under my breath. I was going to start the lesson when I heard a soft voice talking nonsense. Annoyed, I scanned the crowd looking for the culprit- and finding her easily. "You girl stand up!" I shouted.

She stood up immediately. "Why were you wasting your time? You'll end up scoring less in exams if you spend your time here foolishly," I scolded louder than the girl before.

"As if that'll ever happen," she smirked at me in a challenging way. I felt strange. Her eyes were so mature.

"19+45" I asked. I increased the intensity of question.

"64" she answered in less than a second.

"23+1097" I asked.

"1120" she replied, even faster than before. She kept on smirking at me.

"108x78" I asked with a sly grin."

8424 sir.." She took 5 seconds. I was dumbstruck. I myself didn't know it's answer. It was embarrassing. "Who taught you all these?" I asked.

"Mom." She muttered and asked if she could sit. I nodded and told her not to disturb anybody from then. It was very strange for a girl of class two to answer like a student from class Four or Five. Ugh... I forgot to ask her name.
